You will be doing DC voltage amplification for the load cell.
It would be helpful if you are able to use a circuit simulator.
Download the free simulator here:

In the example section of the simulator is a circuit labeled
op-amp integrator .
Open this example, and use the
cut tool to remove the 58 µF capacitor.
The gain for this particular circuit is something like 2000, which may be useful for your particular data acquisition board. The gain value is adjusted by changing the value of R2/R1.
